Node JS SDK Code won't execute

I recently downloaded the SDK for Node JS. When I tried to compile after following sample code from your API, the version of the SDK I installed from NPM threw a syntax error.

Is there a way I can still use the service with Node JS? Thank you

this.isStillAuthenticated = async function isStillAuthenticated(response) {
SyntaxError: Unexpected token function

We can not reproduce the error you are experiencing. Can you give us your sample code please, so that we can carry out more realistic tests ?

Thank you.
